UNITE will encapsulate the common features of cellular, wireless (3G, WMAN, WLAN) and DVB broadcasting to provide a scalable, extendible, evaluation and co-existence Virtual Distributed Testbed (VDT) to investigate cross-layer and cross-system optimization. Its intention is to push back the boundaries on simulation tool design by removing the constraints on abstract modeling of layers. UNITE envisages to have available a complete set of evaluation tools to model protocol behavior within L1 to L3, so that a richer set of cross-layer parameters can be made available for optimization; these cluster of tools may either coexist within an organization, or may be geographically distributed.

UNITE aims to address the aforementioned research challenges by:

- Implementing an efficient, accurate and scalable VDT to support cross-system and cross-layer optimization of heterogeneous systems in a unified manner.

- Using VDT, to investigate, design and evaluate cross-layer and cross-system interactions among next generation radio protocols without neglecting important 
    real-system details.

The Pan-European VDT (an important UNITE innovation) will offer the following key beneficial attributes on a European scale:

- A platform for realization of existing and future radio standards.

- An end-user transparent framework with plug and play features to support cross-system and cross-layer algorithmic testing in a beyond 3G heterogeneous environment.

- The enabler for cross-layer optimization to attain an optimized radio access network solution in view of E2E (End-to-End) performance.

Sigints Description of Work (Research work, experiments, papers, documentation, demos, results) :

In UNITE, Sigint developed at the:
- network layer, software components for interconnecting remote radio/telecom simulators/emulators, for the purpose of constructing much larger scale simulations,
  including cross system/layer simulations for heterogeneous networks, and at the
- application layer, a graphical user interface and data processing modules for the selection of the remote radio/telecom simulators/emulators configuration to be utilized under UNITE simulation framework, for the configuration of the simulation-related parameters, for the processing of user input into UNITE-related data format and for the simulation request. Moreover, Sigint has developed the repository of layer/platform specific algorithms to store the simulation scenarios and algorithms developed by the end user and also the simulation results that are associated with each simulation scenario.
